Quadrapolar magnet generating field gradient effects on kainic acid induced neuronal swelling


There are a number of effects produced by inhomogeneous static magnetic fields like that of Q magnets, the main ones being increasing the pain threshold and dampening sensitized nerves. The following study looked at the effects on cell membrane stabilization.

These effects at a cellular level could help explain the observations of Q magnet therapy on haematomas.

OBJECTIVE: Swelling is a final common pathway to neuronal death following diverse insults that damage the central nervous system. Here we have tested the effect of a static magnetic field on neuronal edema induced by the excitotoxin, kainic acid (KA), in an effort to identify a new treatment strategy.

Effects of Moderate Static Magnetic Fields on Nerve Conduction and its Relevance to Q Magnet Therapy

Pages on the Q magnets  website such as “how Q magnets work” and “magnetic field gradients” describe how inhomogeneous static magnetic fields (iSMF) affect nerve fibres. A recently published study provides further confirmation of the physiologic effects as we have described.

The effects of SMF on nerve conduction are unclear and the underlying mechanisms not well understood. This study focused on the effects of a moderate (iSMF) on membrane excitation and refractory processes on frog sciatic nerve fibres.

Positioning Neuromagnetics in the “window of effectiveness” for magnetic therapy.

Recent studies investigating the therapeutic effects of static magnetic fields propose there likely exists a “physiologic window” of effective magnetic field properties. This is certainly our experience and more research needs to be conducted to understand the parameters of this window for optimal therapeutic effect.

The fact is, there are 7 variables when it comes to the application of static magnet devices. If the offending target tissue (e.g. sensitized C-fibre nerves in spine) is enveloped by an optimized field by correctly applying the most appropriate device, then remarkable outcomes for pain sufferers are sometimes possible. Just like in the case of John with a 27 year history of back pain.

After thousands of patients treated and numerous clinical trials and animal studies, there is now enough evidence to recommend protocols for effective Q magnet placement.

Inhomogeneous static magnetic field (magnetic therapy) effects on TMJ Pain

The type of magnet used is this study is not a Q magnet.
The safety and effectiveness of Q magnets has not been established in the treatment of dental or TMJ pain.


A recent paper studying the effects of an inhomogeneous magnetic field on dental pain was published in the International Journal of Radiation Biology. While the size of the study was relatively small (29 for TMJ pain) and of short duration (5 min), none the less, it demonstrated a significant pain relieving effect over placebo. The magnetic device used in this study was not a Q magnet, but being a multipolar magnet they share many of the same characteristics.

Neuromagnetics as a subset of the broad category magnetic therapy

When you understand the history of magnetic therapy, it’s easy to understand why and how it’s surrounded in mystery and scepticism. However, this does not negate the fact that promising subsets within magnetic therapy such as Pulsed Electromagnetic Fields (PEMF) and gradient modulated magnetic fields like those produced by Q magnets provide significant therapeutic benefits. After all, isn’t a large magnet at the leading edge of medical diagnostics? The MRI illustrates the possibilities.

11 out of the 13 randomised controlled trials relevant to multipolar magnets listed on our website, show positive effects over placebo. Some of the studies such as Vallbona, Costantino, Man and Laszlo showed significant pain relieving and fracture healing effects.

The two studies that showed no effect were Collacott and Cepeda.
Investigating low back pain was Collacott, who used a weak flexible rubber magnet with an effective penetration of around 10mm. This study was unlikely to show a positive effect because it was the wrong type of magnet. It requires a magnet such as the QF28-6 or OF50-3 to penetrate the 30-40mm required to capture the nerve roots and dorsal horn of the spine to be effective for low back pain.
